But none of these for profit companies that are dependent upon xz have funneled any of their gains in there?

I think if that caught on then companies would call it undue burden to sift through all the dependencies they use to make such small payments.

It is a difficult problem. But on the face of it your suggestion seems very reasonable.

I mean this is already a thing to certain degrees right? Virtualization platforms I use both are free for personal use, but not business use, or at least certain feature package use isn’t permitted. What’s the difference? Putting the software under a different license/eula?

In my opinion it is a terrible choice for a company to rely on a dependency like XZ, especially maintained by one person as a hobby, without being able to meaningfully contribute to the maintenance themselves. I just don’t think I can be sympathetic to a company having to maybe bend a rule or two to donate.

This is one of the problems, these companies and other groups just use a dependency maintained by one person (Lasse) without meaningfully contributing to its survival themselves.
